Claims.

The present invention relates to improvements in bus or car window construction., and particularly in the side strap for the window sash, an object being to provide a side strap having a felt or similar covering which will have very easy sliding movement Within the side channel of the Window construction and at the same time will provide an effective weather seal and support against looseness and rattling. It is particularly proposed to provide a covering material for the side strap having a cross-sectional shape adapted to provide relatively Wide clearances at each side, and which has outwardly disposed side channel engaging portions providing an effective weather seal and resilient support for the window sash, the contact of these outwardly disposed portions with the side channel approximating line contact engagement, so that they oifer minimum frictional resistance to the sliding movement of the window as it is raised and lowered.

With the above and other objects in view embodiments of the invention are shown in the accompanying drawing, and these embodiments will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

In the drawing:

Fig. 1 is a fragmentary front elevation showing the lower corner of a window construction having a side strap provided with covering material according to one illustrated exemplary embodiment of my invention.

Fig. 2 is a sectional view, taken along the line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional view of a modified form of covering material, according to my invention.

Fig. 4 is a horizontal sectional view of another modified form of covering material, according to my invention.

Similar reference characters indicate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, the window sash comprises a glass I, having a top rail (not shown), a bottom rail 2, and a pair of vertical side straps 3 connecting the topand bottom rails, only one of these side straps being shown. The side strap is of U-shape channel form in cross-section to receive the vertical edge of the glass, its vertical edges being bent outwardly and rearwardly as at 4 4, the rearwardly bent portions adapted to engage and cooperate with the edges o-f the facing material 5, according to my invention, which is disposed about the side strap. The facing material 5 is in the form of a channel, of generally U-shape cross-section, and is cemented, riveted or otherwise suitably secured about the side strap, this material being of suitable composition simi- 5 lar to felt or leather as regards its wearing and sealing qualities. 'Ihe sides of the covering ma.- terial extend in parallel relation from the intermediate or connecting portion and their forward vertical edges are longitudinally split or bifurcated, as at E, the inner surface of the split portions being curved or inclined to a point with the outer surfaces of the material. The rearwardly extending portions 4 of the side straps 3 engage within the split 6 of the covering matel5 rial, spreading the outer portions thereof so that their edges are outwardly disposed with respect to the outer sides of the material, and in the assembled relation in the casing these outwardly disposed portions constitute the channel engaging or bearing surfaces of the covering material.

The channel within which the side strap of the sash is mounted is of generally U-shape in cross section, and comprises an outside stop of generally right angular form in cross-section having a ange 1 constituting the outer leg of the channel, a base 8, and a relatively narrow flange 9 at its inner end, parallel to the ange 'i and having a recess I 0 at its inner side, the inside stop Il adapted to be engaged over this flange 9 and 30 within the recess Ill to complete the channel," the inside stop being provided with an offset flange portion l2 which embraces the outer side of the flange 9.

A channel strip i3 is disposed within the side 35 l channel and has its forward edges bent inwardly as at I4--l4 to engage the facing material 5, these edges being spaced apart to provide a vertical slot through which the sash lock plunger l5 projects and is adapted to have vertical movement 40 as the window is raised and lowered. The sash lock plunger projects through slots I6 and I'l respectively provided in the side stop 3 and facing material 5. A pressure spring is secured to the rear side of the channel strip and comprises a 45 right angular base portion I 8, spot-Welded, or otherwise suitably secured to the rear face and one side lface of the channel strip, an intermediate spring leaf portion I9 bent from one vertif cal edge of said base portion, and a spring leaf abutment portion 20 bent back from the edge of the spring leaf portion I9, this spring leaf portion 20 preferably having a convex engaging surface 2| for engaging the base of the side channel. In the assembled relation this spring is. compressed between the base 8 of the side channel and the base of the channel strip I3 and presses the latter inwardly against the facing material 5 to yieldingly retain the edge of the window sash against looseness and rattling and at the same time permit it to be easily raised and lowered. A rack member 22 is secured to the inner face of the channel member, as by spot-welding, riveting, or other suitable means, and is .adapted to be engaged by the sash lock plunger I5 to retain the window sash at any desired point of adjustment.

The particular constructions of the outside and inside stops 'constituting the side channel and of the channel strip I3, pressure spring and rack, form no part of the present invention, and it will be understood that any suitable constructions may be employed. Y

The facing material according to my invention engages between the respective side legs 1 and I I of the side channel with a clearance space 23-23 at each side and along the major portion of the sides of the facing material. The outwardly extending split end portions engage the surfaces of the side'legs along very narrow surfaces, suflicient to provide the necessary yieldable support against looseness and rattling, and an effective weather sealing closure, while offering a minimum frictional resistance to the raising and lowering of the window.

In Fig. 3 I have shown a modification of the facing material in which the ends are-split at 24-24 and are substantially right angular in cross section, this form of the invention being produced simply by splitting the ends of straight channel material; In Fig. 4 I have shown a further modification of the facing material in which the outer side surfaces 25-25 diverge outwardly from the intermediate or connecting portion to the forward extremities. In both of these modifications the facing material is engaged about the side strap in a similar manner to the first embodiment, and provides clearance spaces at each side and relatively Vnarrow bearing and sealing surfaces for contact with the legs of the side channel.

I have illustrated anddescribed preferred and satisfactory embodiments of the invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.

Having thus described my invention what I claim and desire to secure by Letters Patent is:-
